摘要

A new genus and two new species of extinct Mesochrysopidae (Neuroptera) are described from the Mesozoic of China: Protoaristenymphes daohugouensis sp. nov., from the Middle Jurassic of Daohugou, Inner Mongolia; and Kareninoides lii gen. et sp. nov., from the Early Cretaceous (Yixian Formation) of Dakangpu, Liaoning Province. The presence of CuP in one hind wing of K. lii gen. et sp. nov. is interpreted as an atavism. Armandochrysopa Nel et al. is regarded as a new junior synonym of Karenina Martins-Neto. Armandochrysopa inexpecta Nel et al. is tentatively transferred to Kareninoides gen. nov.
